About our AHU cleaning in Polstead Heath
Where a building in Polstead Heath has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. If you’re dealing with coils clogged with dust and debris and stale or musty smells from the ventilation, we can put it right, from supply and extract fans, internal panels and heating and cooling coils onwards.
Work in a small place like Polstead Heath starts with agreeing access and timings.
Every visit ends with a written report and photos, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

How the visit works
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes half a day to a full day per unit, with large plant planned over several shifts, and we clear up before we go. Somewhere like Polstead Heath, lanes, gates and parking are worth mentioning in advance.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Clear the space around the work
- Have your last certificate or report to hand

How we price AHU cleaning
We quote each job individually. These are the things that affect it:
- Whether it’s a one-off visit or part of a schedule
- Travel, parking and unloading
- The condition we find in the survey
- How easy every part is to reach
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will go through it with you.
What to send for a quote
To speed up the quote, send us:
- Any symptoms, from odd noises to smells or leaks
- Any previous report or certificate
- The roof, plant room or outside wall the system runs to
- Any access panels or hatches you can see
We don’t publish a price list, because every site is different. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To get going, give us a ring on 0345 646 2711 or send us an email.

Managing agents and facilities teams in Polstead Heath
We also work for facilities teams across offices, schools and healthcare across Essex. Larger estates can be phased building by building to keep disruption down.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.
Common questions in Polstead Heath
Can the work in Polstead Heath be done at night or at weekends?
Yes, we can come after you close and finish before you open. The work in Polstead Heath can fit around your hours. Tell us your opening hours when you ask for a quote.
Will you come out to Polstead Heath?
Yes. Polstead Heath is within the area we cover across London and the South East. A survey first, from pictures or a visit, means we arrive with the right kit.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and we will quote them together.
Can you price the work without visiting?
Yes, for many jobs. Send a few wide photos plus close-ups of panels, filters or grilles, and we usually come back within one working day. Some sites still need a visit, and we will say so.
How much notice do you need?
Book as early as you can for planned work, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
Can you fix a faulty AHU?
We clean the unit and flag faults rather than repair them, with the details in the report.
Do you offer emergency callouts?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.
Will we get paperwork for the AHU clean?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.

Fans and fan sections
The fan section is cleaned with the unit switched off and isolated in agreement with the site.
When to call us in Polstead Heath
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that is the air they breathe for hours on end.
The symptoms we’re asked about most are:
- Condensate trays that won’t empty
- Fan sections that haven’t been cleaned in years
- Air handling units never cleaned inside
- Coils clogged with dust and debris
Ventilation work in and around Polstead Heath is risk-based: inspect, then clean what needs it.
